PURPOSE:To secure accurate movement of print wire driving members and facilitate fitting the members, by a construction wherein radial slits and a plate form member are disposed opposite to a magnetic pole of a coil core, and members for covering groove parts of the slits are affixed to the face and back sides of the plate form member. CONSTITUTION:A side yoke 12 and a closed-end cylindrical yoke 10 are provided with radial slits 13, 11 for permitting driving rods 15 to be oscillated, and the parts of transverse grooves 14 provided near outer ends of the slits 13 are covered on the upper and lower sides thereof by the yoke 10 and a ring from leaf spring 19, whereby the grooves 14 are used as parts for retaining pins 16 of the driving rods 15, and a presser plate 20 is placed thereon, thereby assembling an integral body. Accordingly, a multiplicity of the driving members can be fitted easily and securely without any positional error, by placing the plate form member on one of the affixures, positioningly fitting the driving members in the radial slits and a shaft supporting groove of the plate form member and coveringly fitting the other affixure thereon. |
